Replacing Audible Illusion Preamp Feet


Own an Audible Illusions Preamp that will soon be going onto a maple-shelved rack and want to replace the stock feet with brass audio points that I have laying around in my accessory box. Can I unscrew the stock feet without loosening and releasing something internal to the unit such as a lock nut that can't be retrieved and will forever roll around inside and bug the heck out me?

Leave the stock feet on. Forget the brass spike idea. The maple shelf will provide a balanced sound. The spiked feet on the maple shelf are akin to a video monitor with the contrast and brightness controls cranked up. It didn't do it for me.
BTW I prefered some form of spikes and Stillpoints with my previous MDF and Polycrystal shelfs.
